7.0 Installation
Once the connection has been made, Environmental Control Management can be configured
using an SNMP MIB browser as indicated in the following tables. The Environmental Control MIB
section begins at atiMgmtSysTempMgr (1.3.6.1.4.1.926.1.3.2.4). Status of the Environmental
Control is also available via the Communications Module’s Web page by navigating to ‘Advanced
Configuration’, ‘I/O – Environment’. Ensure the ‘Heater/Cooler Only’ is selected from the drop-
down list.
Set these OIDs to the specified value Functionality
atiMgmtSysTempTemperature (1.3.6.1.4.1.926.1.3.2.4.5) to 5 Heater turns on at 5°C
atiMgmtSysTempHysteresis (1.3.6.1.4.1.926.1.3.2.4.6) to 3 3°C of permitted controller overshoot (in this case, would turn off at 8°C)
atiMgmtSysTempCtrl (1.3.6.1.4.1.926.1.3.2.4.1) to 3 Battery temperature sensor used to control heater setpoint
atiMgmtSysTempMode (1.3.6.1.4.1.926.1.3.2.4.3) to 1 Places controller in heater mode
atiMgmtSysTempActiveState (1.3.6.1.4.1.926.1.3.2.4.4) to 1 Drive pin to the temperature device will go low when heater is on
atiMgmtSysTempStatusInvert (1.3.6.1.4.1.926.1.3.2.4.9) to 1 Sets the polarity of the feedback signal from the temperature device
During operation, the following MIB points will report the current temperature and whether the
